I don't know if this means a thing since we haven't seen police pay any attention to it. Note the place in the yard where it appears a vehicle has recently torn up the grass. I've attached photos as captured from the video and as cropped and marked with red dots (marked by myself).

I am assuming that these may have been caused by LE, or they probably would be marked off so they wouldn't get destroyed.. There is a silver minivan up by the deck that had to get up there somehow. I can't find pictures of the back of the house, but they had to drive around the house one way or the other.
